App1ication filed May 5, 1921. Serial No. 467,120.

To all whom it may concern: I

Be it known that I, JOHN IV. Hnss, of the city of Kitchener, in thecounty of Waterloo, Province of Ontario, Canada, a subject of the Kingof Great Britain, have invented certain new and useful Improvements inthings, to devise improved means for heatfolder plates in advanced- 'ingthefolders andfor slidably supporting the same, and to provide improvedmeans for actuating the folder plates, to provide efficient meansfor-applying pressure to the infolded edges of the material.

I attain my objects by means of the constructions hereinafter describedand illustrated in the accompanying drawings,-in'

which I F ig. 1 1s a plan view of a machine constructed in accordancewith my invention;

Fig. 2- an end elevation of the same, partly in section;

r Fig; 3 a similar view to'fig. 2 with the position and coacting witht'he 'former;

Fig.- 4' a plan View of one of the pressure arms; i i

Fig. 5 a sideelevation of the same; and

Fig. 6 an enlarged cross section of one of the former plates; 1 In thedrawings like numerals of reference indicate corresponding parts in thedifferent figures. Y

l represents a portion of the frame of the machine in which is supportedthe bed 2.

3 aredoublearms 'fulcrumed atone side of the bed'and -carrying the twohalves of the form 4 about whichthe edges of the material operated onare folded. The form,-

it will be noted, is formed in halves with skived overlapping edges sothat the parts of the forms may be slid endwise overone an other. Eachhalf of the form, it will be noted, is connected to one of the doublearms and'these arms are slidable lengthwise of the bed on the shaft 5journalled on the frame. When the machine is in operation these arms aresuitably rocked to raise and lower the. forms and at the proper time areslid lengthwise 011 the shaft, but with these features of constructionthe present invention is not concerned, and apparatus for this purposeis not shown or described.

The form a is adapted to rest on the center part of the bed and with itco-operates four folder plates 6 constructed as hereinafter described.These folder plates are adapted to be moved diagonally inwards towardsthe center of the bed and therefore to close about the form, at. Theplates rest on two bars 7 which extend lengthwise of the bed, theirupper surfaces being slightly above the level of the portion of the bedagainst which the form 4 rests when in its lowered position.

The preferred arrangement of these bars is to form a projecting rib 8 ateach edge of the bar, which is received in grooves formed in the sidesof a recess 9 extending transversely ofthe bed. In each recess isinserted a flat electrical heating element,

preferably in close contact with the underside of the bar. The bars aremade of a material of high heat conductivity and'preferably of'highspecific heat, such, for example, as copper. The folder plates 6, whichslide on this bar, are thus heated b contact therewith. These folderplates also rest on washers 10, preferably of antifric-- 13101111161131,which surround the pins of rollers 11 which form projections extendinginto diagonal slots 12 formed in. the plates .6. Two rollers 11 and twoslots are, of course, necessary for each plate and thesev slots may besuitably arranged'to give any desired direction of movementof thefolding plates towards one another.

The plates are actuated by two heads 13 which are slidable to and fromthe form. Preferably these heads are supported on rollers 14 running onsuitable tracks on the Links 15 are pivframe of the machine. otallyconnected with these heads and with the plate 6, two such links beingemployed.

for each plate. Therefore, as the heads are reciprocated to and from theform, a suit able movement will be given to the plates. As the platesnot only move inwardly towards one another, but as will herein afterappear, require to be slightly tipped to produce a pressure on thefolded edges of the material, the links are given in efiect a Liniversaljoint connection both with the heads and with the plates. lVhile anysuitable construction may be employed, I show ball-headed studs 16connected to the plates and tothe heads, while the links are providedwith divided sockets 17 suitably secured about the heads of the studs.

The heads 13 are actuated by means of two slides 18 vertically movablein suitable guides at opposite ends of the machine. In each slide isformed a diagonal slot 19 into which project projections 20, preferablyformed as rollers. It is evident that by reciprocating the slides thatthe heads may be moved as desired. These slots may be given any suitableshape to give the heads a. uniform movement or a varying movement as maybe required, and the slots are so proportioned that when the slides arereally at their lower limit of movement the ends of the slots willengage the projections 20 and thus tip is applied by means of arms 21,two being preferably employed for each of the'folding plates. These armsare provided with slotted lugs 22 by means of which they are bolted tothe heads, the slots providing means for adjusting to a limited extentthe position of these arms. These arms are provided at their inner endswith means for engagin the upper surface of the folding plates. heengaging means are preferably adjustable. For this purpose I provide ascrew, 23 threaded through the inner end of each arm. The upper end ofeach screw is slotted for engagement with a screw driver, whereby it maybe adjusted in the endof the arm. The lower end of the screw is formedas a ball 24 and a divided shoe 25 is secured in position on the ball soas to have a rocking movement thereon. A second shoe is preferablysimilarly connected to the side of the arm to steady the rear art of theplate and limit the tilting of the p ate. It is not necessary, however,to employ this second shoe except in the case of the outer of the arms21 as will be seen on reference to Fig. 1.

When the folder plates are moved to their inner positions they fold theedges of the strip of material over the form as indicated particularlyin Fig. 3, and the shoes on the inner ends'of the arms 21 then rest onthe portions of the plates which project beyond the supporting bars 7,hence the downward pressure of the arms due to the headsbeing tilted ashereinbefore described will impart a downward pressure to the inwardedges of 27 suitably v secured together by of rivets or screws. Theunder plate 27 prefer bly o s not e tend at he inn r s de to he in edgeo the pl te 26, so hat he latter projects. A separate member 28 formedof a piece of thin sheet Steel is seemed beneath the extended portion ofthe upperv plate 26 and extends beyond the same, The

collar-engaging partof each form which is:

most sub ect to wear is thus easily renewed or changed at any time.

adapted to fit into corresponding recesses; for-med in the opposedplates. This arrange-.' ment is intended to give substantial goon;
